HAMMER ATTACHMENT.

DANIEL M. EDDY, OF TOPEKA, KANSAS.

HAll/IMER ATTACHB/IE N '1.

Application filed November so, 1907.

T all whom it may concern:

Be it known that I, DANIEL M. EDDY, citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented a new and useful Hammer Attachment, of which the following is a specification.

This invention relates to hammers and its object is to provide means whereby an increased leverage may be obtained during the act of pulling nails by means of the hammer, said leverage being obtained by the use of a supplemental fulcrum connected to the hammer head in a novel manner.

Another object is to provide means whereby movement of the nail head in the claw of the hammer is permitted, thus obviating all danger of breaking the nail as a result of the binding action of the claw upon a nail being pulled.

Another object is to provide suitable means for holding a nail so that the same can be driven solely by the use of one hand, the device being particularly designed for driving nails into a ceiling or other structure above the user and which can only be conveniently reached with one hand.

With these and other objects .in view the invention consists of certain novel fGitf/UH-F of construction and combiinitions of parts which will be hereinafter more fully deseri bed and pointed out in the claim.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a side elevation of hammer head embodying the present improvements, one of the positions of the supplemental fulcrum being shown by dotted lines. Fig. 2 is a section through the hammer head. Fig. 3 is a plan view thereof.

Referring to the figures by charmztcrs of reference, 1 designates a head which may be of the ordinary general outline, the same having a butt 2, claw 3, and eye l. The outer laee of the head 1 has an elongated recess 5 one end of which is provided with a socket 6 designed to receive a tongue 7 formed at one end of a plate 5%, said tongue being pivotally mounted within. the socket and upon a pin 9 or other suitable device extending through the walls of the socket. Plate 8 is preferably of the same width as the hammer head and the tongue 7 is angular in outline and designed to bear against a spring 10 which is secured Within the recess 5 and ex tends across a depression 11 in the walls of Specification of Letters Patent.

the recess. Plate 8 constitutes a supplemental iuleruin and the spring 10 by hearing l against the angular tongue 7 serves to hold l the plate either seated within the recess 5 or l extending therefrom. at right angles to the l head as indicated dotted lines in Fig. 1. i llhe inner oradjoining faces of the claw have oppositely disposed elongated grooves 12 l therein which taper toward the convex face l or the claw as clearly indicated. in Fig. 2. l lihese groove are preferably ofdifferent lsizes, and these grooves increase in depth 1 and decrease in width as they approach eye I 4-. Formed longitudinally upon the outer l ace of the eye and adjoining the claw are l converging retar flanges 13 which overl hang the wall ()l the eye and have their ad'- joining edges converging toward the head i l to lorn: a c shaped slot 14-.

l When it is desired to draw a nail the claw 33 is placed in engagei'nent tl'ierewith in the l usual manner and the nail. is designed to be l seated in any one of the pairs of grooves 12 l formed in the claw. It will thus be seen that 1 when the hammer head is rocked during the l act of pulling the nail a certain amount of movement of the claw upon the nail is per-- initlcd witlmut danger of twisting or bending the nail and therefore the chances of ln-ealting oil the nail head are materially re duced. Should it be desired to increase the leverage or to raise the fulcrum oi the hammer the plate 8 is swung outward as indicated by dotted lines in Fig. 1 and constitute a support For the hammer during the drawing operation. llcrelolorc under certain conditions it has been. custoi'nary to place one or more blocks of woody below the han'inicr head but with this device such an. expedient is unnecessary. Should it be desired to drive a nail at a point which can onlf be reached conveniently by one hand of the user the present invention will be :f'oundv advanta goons lfiecause the head of the nail can be insorted under the :llangcs l3 with the stem of the nail projecting through slot 1d. The nail it is to be driven after which. the hannner can and the nail then driven by means of the butt lit will. be seen that a hammer head such as herein described is but little more expensive than an ordinary hammer but is more advantageous because oi the various described uses l to which it may be put.
